Analysis and Concept Evaluation of a Digital Order Processing in B2B Sheet Metal Production for a Machine Manufacturer Today’s quotation and ordering process for sheet metal parts is still strongly defined by many paper-based process steps, manual and experience-based pricing, as well as low conversion rates from quotation to order. Therefore, this master thesis deals with the analysis and concept evaluation of a digital order processing in B2B sheet metal manufacturing. The project work was carried out on behalf of Bystronic, which is a global provider of solutions for sheet metal processing. The company‘s portfolio includes laser cutting systems, press brakes and corresponding automation and software solutions.

The objective includes: A current-state analysis of the existing digital solutions for the preparation of quotations in the sheet metal

Michael Gerber Advisor: Fabio Mercandetti

processing industry and other industries, the determination of problems and needs of Bystronic’s customers and their end customers, the evaluation of the concept addressing these problems and the examination of the concept for its economic efficiency. It was shown which digital solution specifically addresses the current and future problems of the stakeholders and how the company as a machine manufacturer can strategically position itself in this environment, in order to be able to offer customers solutions for the entire end-to-end manufacturing process as a future system provider.

The IIoT Evolution in the Capital Goods Sector The global management consultancy Roland Berger successfully operates in all major international markets. To better support manufacturing OEMs in their digital strategy, this study aims to explore the future of industrial digitization and understand the role of the IIoT and digital twins within that. Interviews were conducted with 25 companies and 15 further experts at the Hannover Messe 2019. The study focusses on machine tool and manufacturing equipment OEMs but also includes the views of automation equipment providers, Philipp Hamm Advisor: Prof. Dr. Sascha Götte

software, platform and cloud players. The insights were used to prepare case studies describing IIoT solutions of today and tomorrow, compared in a cross-case analysis.

Today’s use cases show that OEMs are able to monitor their products and systems with increasing support in the future. This gives OEMs the chance to build business models on predictive capabilities, and push towards autonomy of manufacturing. The study shows a clear IIoT evolution. As OEMs expand their industry boundaries with software and services for maintenance and operational support, this leads to competition in new environments. To secure the industry domain, OEMs flee into coopetition – the new state of the game. Business model innovation, future proof technologies and positioning for platform economy must be key points of focus for OEMs´ digitization strategies.

Marketing Concept for an Innovative Brain Scanner Forecasts assume a further increase of people suffering from dementia.

Nowadays these patients are examined by using Positron-emission tomography (PET) scanners, which unfortunately require much space and are also very costly. To react to this prognosed growing number of people affected, and to offer a less expensive alternative to conventional devices to clinical facilities, two particle physics from the Swiss Federal Institute of Technology in Zurich, Max Ahnen and Janis Fischer, have founded the company Positrigo and developed the Brain- Positron-emission tomography scanner BPET. This innovative PET-Scanner is uniquely designed for the nuclear-medical examination of the human brain. By using the marketing conception, established

Lina Herting Advisor: Prof. Dr. Sascha GĂśtte

within the present research project, this innovative brain scanner should successfully be marketed. The entire work is based on a Lean Canvas, which the author has compiled together with the company.

The Lean Canvas is an adapted version of the Business Model Canvas for Start-ups, showing the present company and market situation.

Based on this, company goals were defined, and economical and psychological marketing goals could be derived. These expect the company to increase its degree of familiarity amongst the target customer segment and break even in the year 2023. To achieve these goals, appropriate customer-oriented and competitive marketing strategies are derived and concrete actions in the field of product, price, communication and distribution are proposed.

Potentialanalyse zur Entwicklung des Schweizer Wasserstoffmarktes in der Mobilität The transport sector accounts for around 1/3 of Switzerland‘s CO2 emissions and must be converted to sustainability: Hydrogen mobility is a solution. The market potential and the attractiveness of a market entry of hydrogen in road transport is described here. An analogy to the NGV market, as well as analyses for stakeholders, PESTE, industry structure, SWOT and sensitivity were methodically prepared and „System Thinking“ applied. The barriers and most important drivers to hydrogen mobility are climate policy measures, energy security and Richard Lüchinger Advisor: Prof. Dr. Sabine SulzerWorlitschek

entrepreneurship. The PEST analysis identified four megatrends: Sustainability, urbanization, individualization and digitalization. Porters 5 forces analyze showed that the barriers to hydrogen mobility are high with important barriers to entry as: Capital requirements, switching costs and the limited number of available models. Analyses of the CLD show that no system variable exhibits critical behavior, the system develops relatively slowly. The influence of R&D on the FC-truck segment is particularly sensitive. This effect can be explained by the importance of the TOC for the purchase decision of a truck.

Infrastructure, competitiveness and customer acceptance are the most important critical success factors. Hydrogen mobility is very attractive due to low-emission propulsion, low maintenance costs, short refueling times and long ranges. After successful implementation of the infrastructure and reduced costs through technical progress, competitiveness is achieved.

New Product Concept Development in the Food Sector The lifestyle of our society is constantly changing and therefore things as well as nutrition are subject to time change. This thesis deals with the development of a concept for a new product in the food sector for the company Emmi.

This is a new product in the Swiss market. As a first step, Emmi has already carried out a preliminary study of the market. The knowledge gained from the preliminary study forms the basis for further work on the master‘s thesis. In a first step the target customer segment could be evaluated by an analysis. Based on a literature research as well as own experiences hypotheses about the needs of the target customer segment were established. These were prioritized by experts and

Philippe Meyer Advisor: Prof. Dr. Christoph Imboden

completed by customer discussions. A specification for the product could then be derived from the list of requirements. The specification forms the basis of the concept variants, which were subsequently developed. These show different marketing possibilities for the product.

The various concepts were analysed together with the company with the aim of deciding on a concept which would then be developed in greater depth.

Verbesserung des Nutzen – Aufwand – Verhältnis von Business Ökosystem Design mit der Trihow-Technologie Business ecosystems will shape and change the future, if literature and the opinions of experts are to be believed. A wide variety of sources indicate that in the future the survival of a company will strongly depend on its embedding in a business ecosystem.

In order to build a business ecosystem or to visualize an existing one, a practical method is needed. Since existing literature and methodological approaches are very theoretical and difficult to apply in practice, in this thesis, a practice-oriented method is to be researched.

Pascal Scherrer Advisor: Prof. Dr. Patrick Link

The main goal is to get a better use - effort - ratio than the existing approaches.

The result of this work includes a very mature prototype for the design of a business ecosystem. This prototype consists of a methodological guide which can be applied with physical elements and a digital support. This results in many new advantages, which distinguish the new method strongly from the already existing approaches.

The newly developed guideline is intended to enable companies to build up new business ecosystems in a practical way or to visualise existing business ecosystems in a workshop. This should help, for example, in an assessment of the current situation to generate new food for thought for improving one‘s own business ecosystem.

Service supply chain optimisation – Applying the D2A framework for printing as a service Today any machine can be digitised and connected; collecting the data is not an issue; what is becoming more critical is how the field data can be exploited to identify the right action to be taken. This creates a very complex problem, as the right data must be transformed so that only the right information, at the right time, in the right form can be delivered to the right decision-maker, independently of the problem domain - e.g. route cause analysis, demand forecasting, productivity optimisation, spare parts delivery. Helping people taking decisions can be seen as a smart service, that is designed on the base of a thoroughly understanding of the business complexity. Ecosystems consist of people and equipment, business objectives and strategies, as well as personal

Oliver Stoll Advisor: Dr. Shaun West

needs, attitudes and preferences (must-haves, nice-to-haves) of each operator. Once these needs are fully understood, information can be elaborated from data to create the right insights. The Data2Action framework provides guidance toward the development of data-driven services. The understanding of why and how customers interact with assets is achieved using the Design Thinking approach.

Optimization of the Knowledge Management of the Rittmeyer AG Rittmeyer develops, produces and sells measuring instruments worldwide. To be globally successful, the business unit Instrumentation has established a global partner network. Rittmeyer has launched a partner program to optimize the relationship in this partner network and to improve the partner knowhow about Rittmeyer products. The first academic paper focused on how this partner program can be improved. In this process it became obvious that the partner portal is the most successful option. The goal of the second academic paper was Benjamin Wunderlin Advisor: Fabio Mercandetti

the evaluation of a software to realize the partner portal. On the one hand, the master thesis deals about the adaption of the evaluated software to the specific needs of the Rittmeyer business partners and tests of the optimized system to go live with the developed system, so that in January 2019 the operation of the partner portal (rittmeyerconnect) can be started. On the other hand, a product-finder application was developed within the scope of this master thesis. The benefit of the partner portal is to offer existing partners further added values. With the product-finder, the partners should be made aware of the extensive application possibilities of the Rittmeyer devices, which can lead to extended partner relationships. In addition to the development of the rittmeyer-connect, a product-finder application for the business unit Instrumentation was designed, implemented and finally published on the homepage of the business unit Instrumentation.

Hangstabilität - Analyse von saisonalen Einwirkungen auf die Bodeneigenschaften In the present work, the seasonal influences on the stability of steep slopes with dilatancy are investigated, with a particular focus on the mobilizable friction angle. Research has shown that infiltration causes plastic deformations in a slope, which leads to a softening of the soil. Due to these seasonal influences, the mobilizable friction angle is slightly reduced with every precipitation.

Based on an analysis of historical near-surface landslides, the connection between landslide activity and intensive precipitation Philipp Bächler Advisor: Dr. AndrÊ Arnold

is recognized. In the case of intensive precipitation, areas on slopes fail, while areas directly adjacent to them remain stable. The reason given in this paper is the different softening of the inhomogeneous slope material. Due to the different mobilizable friction angles, certain areas can mobilize a sufficient friction angle during intensive precipitation and others cannot. This process is simplified by means of a disposition model and plausibilized with stability calculation.

The stress path due to infiltration is analyzed with triaxial-tests and with the help of the cam clay model.

Ultrahochfester Stahlfaserbeton – Implementierung und Anwendung Thoma et. al. hat für die nlfe Berechnung von Stahlbetonbauteilen geeignete mechanische Modelle als sogenanntes „User Defined Material“für das Programm ANSYS Mechanical APDL implementiert.

Dieses bereits erstellte Usermat kann additiv erweitert werden, so dass Faserverbundwerkstoffe mit der nlfe Methode berechnet werden können. Hierfür werden zwei unterschiedliche Rissweiten-Faserspannungs-Beziehungen zur Berechnung der wirkenden Faserspannung am Rissufer implementiert. Für normalen Stahlfaserbeton ist die Beziehung nach Pfyl und für UHFB die Beziehung nach Jungwirth hinterlegt. Die aus diesen Beziehungen resultierenden Faserspannungen je Rissweite werden dann in den entsprechenden bestehenden mechanischen

Josephine Maria Fux Advisor: Prof. Dr. Karel Thoma

Modellen fürgerissenen Stahlbeton aufgerufen und zu den bestehenden Gesamtspannungen in x– und y-Richtung addiert. Zur Verifizierung der Erweiterung werden unterschiedliche Bauteilversuche nachgerechnet.

Die erzielten Resultate stimmen betreffend Steifigkeit und Lastniveau gut mit den Versuchsresultaten überein. Jedoch konnte die, aus der Faserwirkung resultierende, Verformungslokalisation und das dadurch entstehende entfestigende Materialverhalten nach dem Erreichen der maximalen Faserspannung für Bauteile, die durch ihre Belastung nicht per se bereits eine Verformungslokalisation aufweisen nicht erreicht werden. Diese Anpassung bedarf einer tiefgehenden Betrachtung und Variation des Fasergehaltes und der Betonzugfestigkeit über das gesamte Bauteil mit einer geeigneten Wahrscheinlichkeitsverteilung.

Gebäude ohne Heizung und Kühlung in Schweizerischen Klimata Thema dieser Arbeit ist die Untersuchung eines Gebäudes ohne Heizung und aktiver Kühlung in der Schweiz. Ein fiktives Gebäudemodell wurde erstellt und anschliessend untersucht. Dabei wurde der Einfluss von unterschiedlichen Schweizer Klimata auf die raumklimatischen Bedingungen analysiert. Das erstellte Modell wurde mit Bauteilen nach heutigem Stand der Technik ausgestattet. Um dem Anspruch der Erfüllung der thermischen Behaglichkeit gerecht zu werden, wurden modernste Verglasungsarten und Bauteile verwendet. Ausserdem wurde das Modell mit einer Nachtlüftung ausgestattet, um die sommerlichen Wärmelasten durch die kühleren Nachttemperaturen zu kompensieren.

Mittels einer Gebäudesimulation wurde der Einfluss der wichtigsten Gebäudeparameter auf die thermische Behaglichkeit betrachtet. Dabei zeigten sich folgende Erkenntnisse: Die Wärmedämmung der Fassade und die Verglasung hatten den grössten Einfluss auf die raumklimatischen Bedingungen; Die Nachtlüftung hatte einen grossen Einfluss auf die thermische Behaglichkeit; Ein Vergleich der Sensibilitäten der einzelnen Standorte auf die untersuchten Parameter zeigte die Einflüsse dieser Parameter auf. Aufgrund von standortspezifischen Klimaszenarien für die Zukunft wurde die Veränderung der klimatischen Umgebungsbedingungen und deren Einfluss auf die thermische Behaglichkeit im Gebäudemodell untersucht. Die Erkenntnisse dieser Untersuchungen zeigten, dass trotz höherer Umgebungstemperaturen nicht an allen Standorten mit einer geringeren Behaglichkeit gerechnet werden muss.

Verformungsverhalten von Durchstanzplatten aus Recyclingbeton Concrete construction is very common in Switzerland. Unfortunately, the concrete production lives on the gravel resources and the cement production is very energy-intensive, especially of embodied energy. The primary gravel in concrete can be partially replaced with mixed demolition granulate, as an environmentally friendly alternative. The current Code SIA 262 ‘Concrete Structures’ and the Code of practice 2030 ‘Recycling Concrete’ deal conservatively with the punching of recycled concrete slabs, due to missing experimental results. So far, recycling concrete is treated like light weight concrete, which causes a resistance reduction of about 25%. First the necessary theoretical basics for the recalculations are outlined. Those comprise the

Markus Laurent Advisor: Prof. Dr. Albin Kenel

mechanical model from Kinnounen und Nylander with the moment-curvature relations from the Tension-Chord-Model and the Model-Code as well as the used stiffness factors and the failure criterion according to the recommendation for recycling concrete. Secondly the angle dependent flexural stiffness of slabs is covered. The optimization of the stiffness factors follows. 12 experimental slabs are recalculated with the presented moment-curvature relations. Every combination of the stiffness factors is analyzed, to find the best fitting to the experimental results. The thesis ends with the investigation of the angle dependent flexural stiffness of slabs, based on the curvature-fields from the experimental campaigns.

Influence of Skew Reinforcement on the Stiffness of Concrete Plates Even though concrete slabs with skew reinforcement are not as customary as the ones with orthogonal reinforcement, this type of arrangement is getting constantly more widespread, as the architectural complexity of buildings increases. The influence of skew reinforcement on the behavior of concrete plates has not been sufficiently researched, specially the post-cracking phenomena, which can significantly affect stiffness and strength properties.

In the master thesis, a calculation algorithm was developed which Liene Christina Wild Advisor: Prof. Dr. Albin Kenel

allowed the stiffness of concrete slabs with skew reinforcement to be examined. In order to enable the comparison of the influence between parameters in the calculation, the algorithm included different models and material properties. A simplified calculation was performed based on the Compression Field Model using linearelastic material properties and neglecting concrete compressive strain while a more detailed examination of the load-deformation behavior was performed using the Cracked Membrane Model, as it combines the basic concepts of the modified compression field model with the tension chord model, therefore accounting for other effects, such as tension stiffening and compression softening.

Development of Harmonic Balance Methods for a Coupled Pressure-Based Solver Transient simulation of time-periodic flows using conventional CFD (Computational Fluid Dynamics) techniques is computationally demanding and often not feasible in the industry. As an alternative, the Harmonic Balance (HB) method has been developed, which allows only a limited number of frequencies to be calculated. The transient simulation is then replaced by a system of stationary simulations, which are coupled by a time-spectral operator.

The thesis investigates methods to implement HB in a coupled Armando Del Rio Advisor: Prof. Dr. Luca Mangani

pressure-based solver. The focus lies on a favorable stability behavior.

Problems such as rotor-stator interaction in multi-stage axial compressors were at the forefront of HB‘s development. This is the reason why the method was developed for density-based solvers.

Pressure-based solvers have not yet been extensively investigated. For the implementation it is attempted to use the findings of the density-based solvers. The focus lies thereby on implicit time-separate techniques.

Different HB methods have been programmed and compared using the finite volume approach. The behavior was first analyzed for the scalar transport equation and then extended to RANS (Reynolds Averaged Navier-Stokes) flow problems. It has been shown that it is possible to adapt certain HB methods of the density-based solver and use them in a coupled pressure-based solver.

Kombination von Abgaskondensation und Brennstofftrocknung This thesis covers the influence of fuel drying and flue gas condensation on an automatic heating plant that runs on wood chips. To evaluate the influence of these technologies, the mass and energy balances of different plant concepts are calculated and compared. By drying the wood chips with the flue gas of the heating plant, the fuel demand of the plant can be reduced by 9 to 11 %. The fuel reduction due to flue gas condensation is between 17 and 27 %. A combination of these processes does not reduce the fuel demand any further. If the process includes flue gas condensation, the fuel demand decreases with increased water content in the fuel, despite a reduced combustor efficiency.

The fuel demand of the concept with conveyor dryer stays constant

Davis Haude Advisor: Prof. Dr. Thomas Nussbaumer

despite a reduced combustor efficiency due to an increase in the air surplus. In the examination of the heat generation costs, the case with flue gas condensation alone shows to be the most economical.

Analysis of Robustness of Air Lubricated Turbo Compressors with Regard to Humidity and Condensation The application of air lubricated turbo compressors in domains where ambient conditions cannot be controlled (e.g., for mobile fuel cells in vehicles) raises the question of the effects of partial condensation of water vapor on the functionality and reliability of the gas bearing and other parts of the turbo compressor. A theoretical analysis of situations with partial condensation processes reveals that during environmental and operating conditions where condensate can accumulate over a certain period are most critical. In order to identify critical spots in the Lukas Hediger Advisor: Prof. Dr. Mirko Kleingries

turbo compressor and experimentally investigate critical condensation processes under real situations a test stand is developed, constructed and commissioned, which is able to increase the temperature of ambient air on the one hand and the humidity up to saturation state on the other hand. Two sealing gas concepts, which are the impeller-propelled and the high-pressurized sealing gas, of the turbo compressor CT-17-700.GB are compared theoretically and experimentally. In general, an accumulation of condensate is observable on surfaces close to the cooling water and far away from loss sources, e.g. the rear part of compressor, at a constant cooling water temperature below the dew point temperature of the inlet air.

Therefore, for the application in fuel cell vehicles a redesign with a rearrangement of the sealing gas inlet and outlet to parts with a higher concentration of loss sources, e.g. close to the axial bearing, and the use of a thermostatic valve in the cooling water circuit are proposed.

A Numerical Investigation of the Drying Process of an Adhesive Polymer Dispersion This project’s aim was to learn more about the drying process of the adhesive polymer dispersion which the industrial partner uses in its products for building envelopes. The thesis formed a part of an extensive collaboration project between HSLU and the industrial partner. The stated goal of it is, that the production rate shall be doubled while halving the energy required per m2 of polymer dispersion dried. Initially, a series of small scale drying experiments with a maximum of two nozzles and a stationary sample were replicated in a model, simulated, and validated with the experiments’ results to gain a first estimate of the material parameters.

Subsequently, the full drying tunnel, where the paper liner coated with

Matthias Reich Advisor: Prof. Dr. Mirko Kleingries

the polymer dispersion moves through, was modelled and simulated.

This model was in turn validated with measurements from prior experiments executed with that drying tunnel. After the validation, a parameter study was conducted to find what changes of the different parameters, such as inlet temperature or humidity, have on the drying rate.

Modelling of Gas Phase Adsorption Processes The physical principle of adsorption is present in many technical systems. Due to its complexity, modelling and design of such systems is complicated. Available models are often based on mathematical fits rather than on physical equations.

The aim of this master thesis is to model adsorption processes in a very general way using as much physics as possible. This allows for alternative application of the model. After a review of recent scientific literature, best models are identified, complemented and implemented Silvan Schneider Advisor: Prof. Dr. Ulf C. MĂźller

in Modelica language. Dymola is used as modelling environment and enables effective coupling of the multi-domain physical equations.

Finally, the model is checked by test cases found in literature to asses functionality and performance.

Design of Macro Encapsulated Latent Heat Storage Using NTU-effectiveness Method Thermal performance characterization of thermal storage systems employing phase change materials (PCM) has been carried out predominantly through numerical modelling. The simulation of the characteristic of a thermal energy storage (TES) unit using encapsulated PCM spheres is investigated in detail. In this study a design methodology for a thermal energy storage system using the NTU-É› method was developed. In practice a PCM storage system can be described as a heat exchanger in which the heat transfer fluid (HTF) exchanges heat with the PCM at the phase change temperature. The performance of a heat exchanger is described by the heat exchange effectiveness. Whereby the effectiveness is defined as the ratio of the

Benjamin Schroeteler Advisor: Dr. Ludger Josef Fischer

actual heat transfer to the maximum possible heat transfer.

The aim of this work is to develop a simplified design methodology for TES with macro encapsulated PCM spheres. This approach can be used for sizing a TES.

Determination of an Energetically and Economically Efficient System for the Separation of CO2 from Ambient Air Based on Ad- and Desorption Das Zürcher Startup-Unternehmen Climeworks AG entwickelt und produziert Anlagen für die Separation von CO2 aus der Umgebungsluft basierend auf Ad- und Desorptionsprozessen. Die Firma stellte die weltweit erste kommerzielle Anlage dieser Art her und ist somit der Vorreiter dieser Industriesparte. Als potentielle Abnehmer des separierten Treibhausgases werden die Getränke- und Nahrungsmittelindustrie, Gewächshäuser und Hersteller von synthetischen Treibstoffen angesehen. Für die Optimierung der Anlagen soll der Fabian Walker Advisor: Prof. Dr. Mirko Kleingries

Einsatz von alternativen Adsorbensbetttypen untersucht werden.

Abhängig vom gewählten Reaktortyp ergeben sich unterschiedliche Betriebscharakteristiken und technische Änderungen der jetzigen Anlage. Wichtig sind hierbei beispielsweise der Energieverbrauch der Anlage, die CO2 Separationsrate oder die Produktionskosten der Anlage. Es wurden für jeden Reaktortyp verschiedene Konzepte entwickelt, von welchen jeweils die wichtigsten Kennwerte ermittelt wurden. Diese Kennwerte dienten als Grundlage für die Analyse und Evaluation der Konzepte. Das aussichtsreichste Konzept wurde genauer analysiert und grob vordimensioniert. Zuzüglich wurde abgeschätzt, wie sich das Konzept aus energetischer und ökonomischer Sicht im Betrieb verhält und ob es im Vergleich zur jetzigen Anlage Potenzial für eine Systemoptimierung bietet.

Optimierung von Neuronalen Netzen mittels Evolutionärer Algorithmen A Convolutional Neural Network (CNN) is a basic design pattern for a neural network today often used for computer vision related tasks like classification. For a widespread application of the technology, e.g. the use of CNN in an embedded device with limited resources, common networks require too much computational power and networks that are more efficient but still have a good performance are often desired.

To find such network architectures for a given problem is often a time and labour consuming task. In this work the idea to use an evolutionary Fabio Marco Johner Advisor: Prof. Dr. JĂźrgen Wassner

algorithm to optimize a given CNN on a given problem is explored, a concept often referred to as neuro-evolution. An evolutionary algorithm (EA) is a strategy which is inspired by biological evolution with mechanisms like mutation or selection and is often used for optimization problems. A specific algorithm is designed, implemented and tested on two different real-world data sets which cover the task of wheel detection and traffic sign classification. The results show a good performance and a desired behaviour of the algorithm. For the traffic sign classification task the algorithm started from a international challenge winning CNN architecture and reduced the computational power required by a factor of 8 with no accuracy loss, by a factor of 14 with a little accuracy loss of 0.2% and a factor of 21 with an accuracy loss of 0.5%. These experimental results show that neuro-evolution can be successfully used to optimize a CNN architecture for the use in embedded devices.

Development of a Modified Nominal Stress Approach for the Assessment of Welded Railway Structural Parts Welding is a traditional process for assembling large structural parts as they are needed for railway vehicles; especially for frames and structures of train bogies or car bodies. In order to guarantee safety and reliability of the welded parts, Finite Elements Models (FEM) are used to simulate part behaviour under influence of external stresses.

Fatigue testing of critical parts is crucial to determine the lifetime and crack initiation. Welding guidelines such as the DVS 1612, IIW and FKM define security margins that have to be taken into account under determined stress configurations. Better estimation of the safety factors can be done by testing of the components. During this project one sided bevel butt welds are fatigue tested with specific stress

Marco Pizzolato Advisor: Prof. Dr. Udo Lang

configurations and then compared to FE Models. The FE Models use the nominal stress approach and the more calculation intensive notch stress approach to estimate the stress in the welding. A better understanding of the behaviour of the weld root and weld toe means more precise FEM simulations and prediction of the critical spots and fatigue strength. More accurate simulations and lifetime prediction as well as assessment of welding is in the interest of PROSE, an engineering company based in Winterthur, specialized in the development and simulation of railway vehicles.

E-Auto Heimladestation In 2018, 5% of the newly registered cars in CH were electric vehicles.

While it is important to increase the publicly availabe fast charging stations equipment, most drivers charge their electric vehicle at home.

The offer of home charging equipment is diverse and EVTEC is one of the competitors within this market with their product sleep&charge.

They are working on a redesign of this device and some components are developed and evaluated within this thesis. The increasing number of electric vehicles leads to growing energy requirement due to Stefanie Schmidiger Advisor: Prof. Erich Styger

charging sessions being started. Power supply companies strive to keep the load steady on their power network and released new regulations that require home charging stations to be controllable by them. They will most likely use ripple control signals to influence the charging sessions. A prototype ripple control receiver is to be developed within this master thesis that can later be integrated into the revised sleep&charge device. Furthermore, proposals are given as to how the requirements can be met for the regulations on residual current devices within charging stations and a new display is suggested that could replace the currently used LCD character display. End tests showed that the implementation could be much better than the performance of commercially available ripple control receivers. Recommendations are given concerning the implementation of DC leakage current detection for residual current devices and some proposals for display technologies to be used for the next generation of home charge devices.

Analysis and evaluation of damping characteristics from additive manufactured components with powder cavities This thesis analyses the possibility of improving the vibration damping effect from additive manufactured components, which includes cavities filled out with powder. The used additive production process is the selective laser melting (SLM). The cavities are produced during the layered production of the part by not melting the powder in the areas of the cavities. This powder cavities increases the damping of mechanical vibrations on the component. The aim of this work is to quantify, how strong this damping effect of the powder is, and what the connection between the size of the powder volume and its damping coefficient is. The damping coefficient depends not only on the material but also on the design of the component. This thesis starts

Niklaus Schneider Advisor: Prof. Dr. Udo Lang

with the theoretical research of the calculation and measurement methods of damping coefficients and continues with the measurement of damping coefficients. The measurements are done by different dampers with different sizes of cavities with powder. These measured damping coefficients are used to evaluate the influence of the relative powder volume inside the component. The result is that a larger powder volume leads to a larger damping coefficient, and the frequency influences the damping coefficient.

ICT - Embedded Systems plays a central role in the melting point of information technology and electronics: With the Master‘s degree, our graduates are excellently prepared for the future. With the theory, the project-based work and the intensive supervision by advisors, they are able to anticipate and actively shape the future.

Only with innovative approaches and new technologies can the challenges of the future be mastered.

We congratulate the graduates on their achievements and look forward to the future.
